Calin ITU, Maria Luminita SCUTARU, Sorin VLASE

Abstract


The chassis represents, along with the engine and transmission, one of the vital components for a car. This is the reason why the subject is intensively studied in specialized literature and numerous solutions are proposed. In this paper, we deal with the particular case of a racing car, which imposes additional requirements regarding the requests that appear in the structure and safety in case of an accident. The method used in the work was the finite element method, which proved to be a useful, stable method of modeling and solving problems, verified by practice. The modeling and discretization was done using the well-known classical procedures The eigenfrequencies and eigenmodes of vibration of chassis used in Formula Student was obtained. The research used the experience of some pilots on such cars, to identify which are the sensitive parts of the assembly. The obtained results were communicated to the design team and thus the solution of a racing car was reached which was successfully used in student car competitions.
